摘要
针对目前原油中石油磺酸盐难以检测的问题,利用高效液相色谱柱切换技术建立了一套油相内石油磺酸盐的分析装置,通过多色谱柱联用及切换阀的改向作用,使复杂样品能够直接进样分析。采用新方法对孤东油田七区二元驱油水两相中石油磺酸盐的分析表明,石油磺酸盐在油水两相有其合理的分配,研究结果能准确地反映石油磺酸盐的分布规律。
Facing the issue that petroleum sulfonate in oil is difficult to be detected,an unit is now set up for analyzing the petroleum sulfonate in oil phase by means of HPLC switching technique. The complicated samples can be directly analyzed by using multi -chromatography column and change - over cock. The petroleum sulfonate in oil and water phases of sulfonate/polymer flooding in No. 2 area of Cudong Oilfield is analyzed using the new method. The result shows that there was such a distinct distribution of petroleum sulfonate in oil and water phases that it could reflect the rule of petroleum sulfonate distribution.
